How to find out what version of webdeploy/msdeploy is currently installed? - powershell

Question

I'm looking for something like a Powershell script to check if msdeploy is installed and if it is, what version
I've considered checking "c:\Program Files\IIS" and checking for MSDeploy installations there, but is this always guaranteed to be the install location?
I need this to work on any given server machine

Answer 1

When msdeploy is installed (no matter where in the file system), it will add its install path to the registry at;
HKLM\Software\Microsoft\IIS Extensions\MSDeploy\<version>\InstallPath
and its version information to;
HKLM\Software\Microsoft\IIS Extensions\MSDeploy\<version>\Version
...where <version> is currently 1, 2 or 3 depending on the WebDeploy version you have installed.

Answer 2

Depends on what you consider "version". By the folder name "c:\Program Files\IIS\Microsoft Web Deploy V3", the version is 3, but if you run msdeploy.exe, the version is 7.X

Answer 3

This is what I did in my PowerShell script:
$WebDeployInstalled = Get-WmiObject Win32_Product | ? {$_.Name -like '*Microsoft Web Deploy*'}
if ($WebDeployInstalled -eq $null)
{
$msg = "Microsoft Web Deploy is not found on this machine."
Write-host -BackgroundColor Red -ForegroundColor White $msg
return
}
else
{
$MSDeployPath = Get-ItemProperty "HKLM:\SOFTWARE\Microsoft\IIS Extensions\MSDeploy\*" | Select-Object InstallPath
$MSDeployPath = $MSDeployPath.InstallPath
}

You can use the following PowerShell snippet:
$installPath = $env:msdeployinstallpath
if(!$installPath){
$keysToCheck = #('hklm:\SOFTWARE\Microsoft\IIS Extensions\MSDeploy\3','hklm:\SOFTWARE\Microsoft\IIS Extensions\MSDeploy\2','hklm:\SOFTWARE\Microsoft\IIS Extensions\MSDeploy\1')
foreach($keyToCheck in $keysToCheck) {
if(Test-Path $keyToCheck){
$installPath = (Get-itemproperty $keyToCheck -Name InstallPath -ErrorAction SilentlyContinue | select -ExpandProperty InstallPath -ErrorAction SilentlyContinue)
}
if($installPath) {
break;
}
}
}
If you wrap it into script block then you can call it in remote session.
